Generative, Algorithmic, Parametric and AI-Assisted Design Amheba Bookcase by George Šmejkal Organic bookcase called Amheba is driven by algorithm, which contains variable parameters and set of rules. Concept of Topological optimization is used for lightening the structure. Thanks to precise jigsaw logic is possible to decompose and transfer it, anytime. One person is able to carry by pieces and assemble 2,5 meters long structure. Technology of the digital fabrication was used for realization. Whole process was controlled only in computers. Technical documentation was not necessary. Data was sent to the 3-axis CNC machine. Result of whole process is lighweighted structure.
